Question

i) 2⁵⁵× 2⁶⁰ — 2⁹⁷×2 ¹⁸
ii) (1³+ 2³+3³)-⁵÷²​

Answer 1

CORRECT ANSWERS :-

(i) 0

see the  calculation given below :-

       $2 ^{55} * 2^{60} - 2^{97} * 2^{18} \\=2^{55+60} - 2^{97+18} \\=2^{115} - 2^{115} = 0$

(ii)1/6⁵

see the calculation given below :-

$( 1^{3} + 2^{3} + 3^{3} ) ^{\frac{-5}{2} } \\= ( 1 + 8 + 27 )^{\frac{-5}{2} } \\= (36)^{\frac{-5}{2} } \\\ = [ (6)^{2} }]^{\frac{-5}{2} \\\ = (6)^{2*\frac{-5}{2} } \\=(6)^{-5} \\= \frac{1}{6 ^{5} }$
