Question

for question 4, what you have is correct, you just need to replace the question marks with the correct number

Answer 1

@jhonyy9 could you help me?

Answer 2

what mean this ? from this radical you need getting 4 ? and for this you need write there the index of radical or what ?

Answer 3

this 4 in front of radical mean question nr. 4 ?

Answer 4

@TETSXPREME any idea please about this ?

Answer 5

@supie

Answer 6

do you understand this posted problem ?

Answer 7

tbh idek is there 2 answers?

Answer 8

2 answers ? what is the question ?

Answer 9

25 7/2 with the original questions but then I answer \[\sqrt{25}^7\]

Answer 10

ok and what you need to do now ? do you need simplifie this radical or calcule this radical or what ?

Answer 11

so you can write again the 25 like square of how many ?

Answer 12

he just said that i need to replace to question marks with a number

Answer 13

ok but what mean this 4 in front of radical ?

Answer 14

the question wan be

25^(7/2) = ?

Answer 15

yes

\(\color{#0cbb34}{\text{End of Quote}}\)
the 4 was just the number of the problem

Answer 17

ok than this is very very easy

just rewrite the 25 like a power of 5

Answer 18

25 = 5^?

Answer 19

5^2

Answer 20

exactly

Answer 21

so you have there in this way

(5^2)^(7/2) = ?

what you need to do with exponents in this case ?

Answer 22

78125

Answer 23

\[(5^2){^{\frac{ 7 }{ 2 }}} = ?\]

look please

Answer 24

5^7

Answer 25

perfect

Answer 26

so the 5 would have to go one top

Answer 27

no

this mean 5 on power of 7

Answer 28

he said that the only thing that was missing was a number where the question mark is

Answer 29

(number 4)

Answer 30

hence is more understandably

\[25^{\frac{ 7 }{ 2}} = ?\]

in this case just you need to know that when there is a fractional exponent so the denominator of this fraction mean always the index of radical

for example

\[x^{\frac{ 2 }{ 3}} = \sqrt[3]{x^{2}}\]

Answer 31

ok ?

Answer 32

questions ?

Answer 33

so \[\sqrt[5]{25}^7\]

Answer 34

how you get this index of 5 ? there is on exponent 7/2 so 2 will be the index of radical

Answer 35

ok ?

Answer 36

\[\sqrt[2]{25}^7\]

Answer 37

\[\sqrt{25^{7}}\]

in this way

Answer 38

but he said that there need to be a number

Answer 39

no

the text of your posted problem said that write these exponential expressions in radical form

Answer 40

oh ok thank you

Answer 41

anytime
