Answer 1

Just give me the equations and I will help1 :)

@Cruznatalie150

Answer 2

(a-b)=0

where b is the solution

Answer 3

select alll that apply
these are multiple choice answers

Answer 4

i dont see the answers

Answer 5

1. 2^3x=8^3x

Answer 6

2. 4^x=4^5x-20

Answer 7

just substitute 5 for x in each equation and check which will be correct

Answer 8

3. 4^x+6=9^x+8

Answer 9

4. 2^x=6^x-3

Answer 10

i did but i got stuck on 3

Answer 11

this is simplifying radicals

Answer 12

4^3==4*4*4=64

Answer 13

if you could explain to me step by step

Answer 14

but its just 4^x it dosent have a varriable

Answer 15

when x = 5, 4^x = 4^5 = 1024

Answer 16

4*4*4*4*4 = 4^5

Answer 17

oh ok so then what would be the answer or how would i solve it @welshfella

Answer 18

Answer 19

for number 2
left side = 4^5 = 1024
right side = 4^(5(5) - 20) = 4^5 = 1024

so?

Answer 20

@AlexandervonHumboldt2 @welshfella like for is equal to 5 right question 4 i substituted them in divided by 2 both sides

Answer 21

beause it asking has a solution to 5

Answer 22

so then 2 would work

Answer 23

??
the left side = right side
Therefore x = 5 is a solution to this equation.

Answer 24

Yes equation 2 has the solution x = 5.

Answer 25

DOES EQUATION 4 HAVE SOLUTION FOR 5 I THINK IT DOES BUT AM I RIGHT

Answer 26

No
LHS = 2^5 = 32
RHS = 6^(5-3) = 6^2 = 36
