simplify (910^{10})(3*10^{20})

simplify

(9 \cdot 1 0^{10}) \cdot (3 \cdot 1 0^{20})

1 0^{30} \cdot 27

Decimal Notation

2.7 E 31

Solution steps

(9 \cdot 1 0^{10}) (3 \cdot 1 0^{20})

Apply exponent rule:

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

1 0^{10} \cdot 1 0^{20} = 1 0^{10 + 20}

= 9 \cdot 3 \cdot 1 0^{10 + 20}

Add the numbers:

10 + 20 = 30

= 9 \cdot 3 \cdot 1 0^{30}

Multiply the numbers:

9 \cdot 3 = 27

= 1 0^{30} \cdot 27

(8.1 \cdot 1 0^{15}) \cdot (0.6 \cdot 1 0^{6})

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

(π (2)^{2} (\frac{5}{3})) 2

(e^{x}) (2 e^{x}) (e^{- x})

(e^{- x}) (\frac{1}{1 + e ^{x}})
