Question

PLEASE HELP URGENT!

Answer 1

simplify the square root of 49a^4

7a
7a^2
7a a squared
7a^2 a squared

Answer 2

i think it's 7a^2

Answer 3

am i right??

Answer 4

we are going to use the property of sqrt(ab) =sqrt(a)*sqrt(b) so in your case we have sqrt(49a^4) = sqrt(49)*sqrt(a^4) = 7a^2 so your right :)

Answer 5

yeah :)
stay turned i HATE this module lost of questions :(

Answer 6

you could do it just keep practicing

Answer 7

i already did most of them here's another Q

Answer 8

HELP PLEASE

Answer 9

ok so we have sqrt(z^7)right just try to think for this one you know sqrt(z^2) is just z correct

Answer 10

z z^3 squared?

Answer 11

so lets just right z^7 as z^2*z^2*z^2*z do you see what i am trying to do?

Answer 12

ok i see now it's EXACTLY like another lesson :)

Answer 13

and now let us use the property that i wrote before and apply it to there and write this as

sqrt(z^2)*sqrt(z^2)*sqrt(z^2)*sqrt(z)

Answer 14

now could you obtain the final answer?

Answer 15

yep.........

Answer 16

if i have anymore Q could you please try and answer them i'll give you best answer everytime :)

Answer 17
