Question

Please solve this its sooper dooper urgent..... no cheatin with me. plssss Write following in exponential form with a negative exponent: a. 243/32 b. 125/37 x 25/9 c. 5/3 x 5/3 x 5/3 x (-7/8) x( -7/8) x (-7/8)

Answer 1

SoluTion :-

$\sf {(a) \ \frac{243}{32}}\\\\\\\sf {= \frac{1}{\frac{243}{32}}}\\\\\sf {=\frac{32}{243}^{-1} }$

_______________

$\sf {(b) \ \frac{125}{37}}\\\\\\\sf {= \frac{1}{\frac{125}{37}}}\\\\\sf {=\frac{37}{125}^{-1} }$

________________

$\sf {(c) \ \ \frac{5}{3} \times \frac{5}{3} \times\frac{5}{3}}\\\\\\\sf {= \frac{5}{3}^{3}}\\\\\sf {= \frac{1}{\frac{5}{3}^{3}}}\\\\\sf {= \frac{3}{5}^{-3}}$

________________

$\sf {(d) \ \frac{-7}{8} \times \frac{-7}{8} \times \frac{-7}{8}}\\\\\\\sf {\frac{-7}{8}^{3}}\\\\\sf {\frac{1}{\frac{-7}{8}^{3}}}\\\\\sf {\frac{-8}{7}^{-3}}$
