simplify (210^8)(610^{24})(6.4*10^{23})

simplify

(2 \cdot 1 0^{8}) \cdot (6 \cdot 1 0^{24}) \cdot (6.4 \cdot 1 0^{23})

7.68 E 56

Solution steps

(2 \cdot 1 0^{8}) (6 \cdot 1 0^{24}) (6.4 \cdot 1 0^{23})

Apply exponent rule:

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

1 0^{8} \cdot 1 0^{24} \cdot 1 0^{23} = 1 0^{8 + 24 + 23}

= 2 \cdot 6 \cdot 6.4 \cdot 1 0^{8 + 24 + 23}

Add the numbers:

8 + 24 + 23 = 55

= 2 \cdot 6 \cdot 6.4 \cdot 1 0^{55}

Multiply the numbers:

2 \cdot 6 \cdot 6.4 = 76.8

= 1 0^{55} \cdot 76.8

Convert element to a decimal form

1 0^{55} = 1.0 E 55

= 76.8 \cdot 1.0 E 55

Multiply the numbers:

76.8 \cdot 1.0 E 55 = 7.68 E 56

= 7.68 E 56

(x + 9)^{2}

(4.1 \cdot 1 0^{- 2}) (2 \cdot 1 0^{- 1})
