Question

hllo please solve this question. class 8 ch 3 exponents and radicals . full explanation ​

Answer 1

Step-by-step explanation:

$3 \times {16}^{ \frac{3}{4} } \\ = 3 \times {2^{4} }^{ \frac{3}{4} } \\ = 3 \times {2}^{3} \\ = 3 \times 8 = 24$

$2 \times {27}^{ \frac{ - 2}{3} } \\ = 2 \times {3^{3} }^{ \frac{ - 2}{3} } \\ = 2 \times {3}^{ - 2} \\ = \frac{2}{9}$

$2 \times {9}^{ \frac{3}{2} } \times {9}^{ \frac{ - 1}{2} } \\ = 2 \times {9}^{ \frac{3 - 1}{2} } \\ = 2 \times 9 \\ = 18$
