Final answer:
The value of the expression
, which simplifies to
.
Step-by-step explanation:
The value of the expression
is determined by applying the laws of exponents. To subtract these expressions with exponents, convert the subtraction into a division:
- Express the subtraction of two exponentials with the same base as the base raised to the difference in their exponents:

- Apply the rule for division of exponents with the same base: subtract the exponent of the divisor from that of the dividend to get the new exponent:

- Simplify the exponent:
.
Thus, the expression
, which is
.
