simplify (4x^{102})x(2.1x^{107})

simplify

(4 x^{102}) x (2.1 x^{107})

8.4 x^{210}

Solution steps

(4 x^{102}) x (2.1 x^{107})

Apply exponent rule:

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

x^{102} x x^{107} = x^{102 + 1 + 107}

= 4 \cdot 2.1 x^{102 + 1 + 107}

Add the numbers:

102 + 1 + 107 = 210

= 4 \cdot 2.1 x^{210}

Multiply the numbers:

4 \cdot 2.1 = 8.4

= 8.4 x^{210}

(2 c) (2 c^{9})

e^{- 0.46209 \cdot 14}

8.2625 \cdot 1 0^{- 3}

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

e^{- 0.46209 \cdot 18}
