Question

26. Find the value of x if (-3/8)² × (-3/8)⁶ = (-3/8)^2x-5​

Answer 1

Answer:

x=6.5

Step-by-step explanation:

(-3/8)^(6+2)=(-3/8)^(2x-5)

6+2=2x-5

8=2x-5

2x=13

x=6.5

Answer 2

Answer:

x= 6.5!!

Step-by-step explanation:

As we can see,

same base getting multiplied with different powers.

Therefore, powers are added!

${(\frac{ - 3}{8})}^{2 + 6} = {(\frac{ - 3}{8})}^{2x - 5} \\ solving \: powers \\ 8 = 2x - 5 \\ 8 + 5 = 2x \\ 13 = 2x \\ \frac{13}{2} = x \\ 6.5 = x$
