(2.9X10^5)X(3.4X10^3 in standard form
Evgesh-ka [11]

By using exponent, it can be verified that

(2.9 \times 10^5) \times (3.4 \times 10^3) in standard form is 9.86 \times 10^8

What are exponent?

Exponent tells us how many times a number is multiplied by itself.

For example : In 2^4 = 2 \times 2 \times 2 \times 2

Here, 2 is multiplied by itself 4 times.

If a^m = a \times a \times a ... \times a (m times), a is the base and m is the index.

The laws of index are

a^{m + n} = a^m \times a^n\\a^{m - n} = \frac{a^m}{a^n}\\(\frac{a}{b})^m = \frac{a^m}{b^m}\\(ab)^m = a^m b^m\\a^0 = 1\\a^{-n} = \frac{1}{a^n}

The given exponent is

(2.9 \times 10^5) \times (3.4 \times 10^3)\\9.86 \times 10^{5+ 3}\\9.86 \times 10^8
