Who knows what 5 to the power of 2 i

Answers

if you mean 5^2 and not 5^2i then
5^2 just means 5 times itself,twice or 5 times 5 or 25

if you meant 5^2i
i=√-1
so law of exponents says a^(xz)=(a^x)^z so
5^2i=(5^2)^i or (25)^i
the answer (if you wanted 5^2i) is 25^i

IF YOU MEANT 5^2 then the answer is 25

25. You just do
5*5 to find out powers! for example, 2 to the power of six is just like
2*2*2*2*2*2
that is
64

Your question's answer is 25.
Thank you!

If f(x) varies directly with x and f(x) = 50 when x = -10, then what is f(x) when x = 15

Answers

The required proportional value of the f(x) is given as -75 when x = 15.

What is proportionality?

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directlyproportional or inverselyproportional to each other.

Here,
As
f(x) ∝ x
So
f(x₁) / f(x₂) = x₁ / x₂

Substitute the values in the above equation,
50 / f(x₂) = -10 / 15
f(x₂) = -75

Thus, the required value of the f(x) is given as -75 when x = 15.

#SPJ2

f(x)=50 x= -10

If x=1, then f(x)=50/-10 = -5

Therefor, when x=15, f(x) = 15*-5 = -30
