simplify (2.110^7)(410^5)

simplify

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

8400000000000

Solution steps

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

Apply exponent rule:

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

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

= 2.1 \cdot 4 \cdot 1 0^{7 + 5}

Add the numbers:

7 + 5 = 12

= 2.1 \cdot 4 \cdot 1 0^{12}

Multiply the numbers:

2.1 \cdot 4 = 8.4

= 1 0^{12} \cdot 8.4

Convert element to a decimal form

1 0^{12} = 1000000000000

= 1000000000000 \cdot 8.4

Multiply the numbers:

8.4 \cdot 1000000000000 = 8400000000000

= 8400000000000
