Question

give me answers one by one .solve 1,2,4,5.​

Answer 1

$\mathfrak{Answer-}$

(1) As we know,

$\boxed{a^{m}÷a^{n} = a^{m-n}}$

Hence, ${3^{7} ÷ 3^{4} = 3^{7-4}}$ = 3³ = 27

(2) Similarly using the above law,

${5^{6}÷5^{2}=5^{6-2}}$ = 5^4 = 625

(4) As we know,

Answer 2

1)3×3×3×3×3×3×3/3×3×3×3

the cut down 4 threes from denominator and 4 from numerator

Answer=3to the power 3.

2)5×5×5×5×5/5×5

same do like first

@=5 to the power 3

3)3×3×3×3×3×3/3×3×3

@=3to the power 3

{same as first and second}

4)-2to the power5+3+2

@=-2to the power 10.
