simplify (2x10^5)x(4x10^7)

simplify

(2 x 1 0^{5}) x (4 x 1 0^{7})

1 0^{12} \cdot 8 x^{3}

Solution steps

(2 x \cdot 1 0^{5}) x (4 x \cdot 1 0^{7})

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

1 0^{5} \cdot 1 0^{7} = 1 0^{5 + 7}

= 2 xx \cdot 4 x \cdot 1 0^{5 + 7}

Add the numbers:

5 + 7 = 12

= 2 xx \cdot 4 x \cdot 1 0^{12}

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

xxx = x^{1 + 1 + 1}

= 2 \cdot 4 x^{1 + 1 + 1} \cdot 1 0^{12}

Add the numbers:

1 + 1 + 1 = 3

= 2 \cdot 4 x^{3} \cdot 1 0^{12}

Multiply the numbers:

2 \cdot 4 = 8

= 1 0^{12} \cdot 8 x^{3}

f (2) \cdot f^{- 1} (3)

3 - x 4 - 2 x

(4 a^{2}) (5 a^{3})

8500 e^{- 0.3 (10)}
