Question

5{√a×(b²)}/5√c where a= (.81)⁴ b= 2.7 c= (90)4

Answer 1

Answer:

$\frac{5( \sqrt{a} \times b {}^{2} )}{5 \sqrt{c} } = \frac{5( \sqrt{(0.81) {}^{4} } \times (2.7) {}^{2} }{5 \sqrt{90 {}^{4} } } \\ \frac{5(0.81) {}^{ \frac{4}{2} } \times (2.7) {}^{2} }{5(90) {}^{ \frac{4}{2} } } \\ \frac{5 \times (0.81) {}^{2} \times (2 .7) {}^{2} }{5(90) {}^{2} } \\ \frac{5 \times 0.6561 \times 7.29}{5 \times 8100} \\ \frac{23.914845}{40500} \\ 5.9049 \times 10 {}^{ - 5}$
