Answer:

Explanation:

With exponential equations, one approach is to make the bases on both sides the same.

=

1250

2

n

Now we can compare the indices of like bases.

n

=

1

n

=

8

n

4

=

4

n

=

8

Do not be tempted to multiply the

2

and

5

!

The indices are different so you may not.

Answer:

2^n-7*5^n-4=1250

2^n-7*5^n-4=2×5^4

now we are comparing on the power.

n-7=1 n-4=4

n=8. n=8

thair for

value of n is 8
