Answer 2

Step-by-step explanation:

[i] (1st step)=we will divide 24÷8 and -9÷3

then it will come 24÷8=3 and -9÷3=-3

(2nd step)=we will multiply 3×(-3)=-9 will be your 1st answer

[ii] (1st step)= according to question it is saying that we have to subtract 5 by 24 with -7 by 24

(2nd step)= as the denominator of both fractions are same we will direct subtract both numerators

(3rd step)= when we subtract 5-(-7) it will give us 12 . so 12 will be your answer

[iii] (1st step)= third question answer will be,yes 225 is a perfect square of 15 . so 15 will be your answer.

[iv] (1st step)= 4th question answer will be square root of 8100 is 90
