Answer:
B. 1/13²
Step-by-step explanation:
oh dear me, what is the true original expression ?
13-7×135 ?
that would be 13 - 945 = -932
or
(13-7)×135 = 6×135 = 810
I guess, since this all does not fit with any of the answer options, you meant
(13^-7) × (13⁵)
in that case remember, when multiplying the same base unit, we keep the base unit and add the exponents as the new exponent.
-7 + 5 = -2
so, it is
13^-2
that "-" on the exponent means 1/...
so, it is
1/13²
