Answer 1

Explanation:

Answer:

328

Step-by-step explanation:

Assume that the given expression is

4\times 81^{-\frac{1}{2}}\times (81^{\frac{1}{2}}+81^{\frac{3}{2}})4×81−21×(8121+8123)

Using the power property of exponent.

4\times (81^{\frac{1}{2}})^{-1}\times (81^{\frac{1}{2}}+(81^{\frac{1}{2}})^3)4×(8121)−1×(8121+(8121)3) [\because a^{mn}=(a^m)^n][∵amn=(am)n]

4\times (9)^{-1}\times (9+(9)^3)4×(9)−1×(9+(9)3)

On further simplification.

4\times (9)^{-1}\times (9+729)4×(9)−1×(9+729)

4\times (9)^{-1}\times 7384×(9)−1×738

Using the negative power property of exponent.

4\times \frac{1}{9}\times 7384×91×738 [\because a^{-n}=\frac{1}{a^n}][∵a−n=an1]

Cancel out the common factors.

4\times 824×82

328328

Therefore, the value of given expression is 328.
