Question

what is : 10^3 * 10^4
18^10 divided by 18^2
please give explanation also....

Answer 1

10³ * 10⁴ = 10^³⁺⁴ =10⁷

this is the first exponental law ...which says that x^a *x^b = x^a+b

18¹⁰ / 18² = 18¹⁰⁻² = 18⁸
this is the second exponents law which states that x^a / x^b = x^a-b

hope this helps.......................

Answer 2

10³ * 10⁴ = 10^³⁺⁴ =10⁷

this is the first exponental law
which says that x^a *x^b = x^a+b

18¹⁰ / 18² = 18¹⁰⁻² = 18⁸
this is the second exponents law which states that x^a / x^b = x^a-b
