5^y×20^y=10000
(5×20)^y=10000
100^y=10000
100^y=100²
Comparing both sides we find
y=2
(5×20)^y=10000
100^y=10000
100^y=100²
Comparing both sides we find
y=2
InfinityMS:
(2×5)^y=1000
10^y=1000
10^y=10^2
So by comparing both sides y=2
I hope I have solved Ur question
Okay good luck happy studies
its correct answer is 3 my friend
Opps sorry that's 10^3 ya so y=3
I m sorry by mistake I wrote that
okay

According To The Question →
5^y × 20^y = 10000
[So, As we know the rules of exponents ,
aⁿ × bⁿ = (ab)ⁿ]
or, (5×20)^y = 10000
or, 100^y = 10000
or, 100^y = 100^2
[ As , we know rules of exponents -
if, a^m = a^n , then m=n]
or, y = 2
Answer→ Value of y = 2.

can i ask more questions
Sure
Pls post it we will try answering it to best of our knowledge
yep
find x if (256)^1/3=x multiply (4)^1/3
(256/4)^1/3=x
So it will be 64^1/3=x
64^1/3=4
So x=4
