Question

if 10^2y=25×4 then find the value of 10^-y​

Answer 1

Answer:

${10}^{2y } = 100$

${10}^{2y} = {10}^{2}$

$as \: bases \: 10 \: is \: common \: on \: \\ both \: sides \: we \: can \: tell \\ 2y = 2$

$y = \frac{2}{2}$

$y = 1$

Answer 2

Step-by-step explanation:

10^2y = 25x 4

10^2y = 100

( 10^2)^y = 10^2

10^y = 1

y = 1

10^-y = 1/10
