Answer 1

Answer:

q1. i) 3^3 =27

27 inverse = -27

ii) 10^-10 = 1^10/10^10

=1/1000000000

inverse = 10^10/1^10

q2. standard form i)234000000000=

200000000000 + 30000000000+4000000000

ii)0.000000001275= 1000+200+70+05

q3.

i)3.02 x 10^-7

100000000 x 3.02=302000000

ii)7.54x 10^5

7.54 x 1000000 = 7540000

q4. find value : (2^0 + 4^-1) 2^2

= ( 1 + 1/4) 4

(5/4)4

5/4x4

=5

q5. i) (-5)² x (-5)^-3

= 25 x 1/-5 x 1/-5 x 1/-5

-0.2
