Work out in a standard form. <br>A) 2.1x 10^-5 ÷7 x 10^-2

EleoNora [17]

$\huge\underline{\underline{\boxed{\mathbb {SOLUTION:}}}}$

<h3>Given:</h3>

▪ $\longrightarrow \sf{\dfrac{2.1 \times {10}^{5} }{7 \times {10}^{ - 2} } }$

First, rewrite the numerator in such a way that the coefficient 2.1 becomes 21:

$\small\longrightarrow \sf{\dfrac{21 \times {10}^{ - 6} }{7 \times {10}^{2} } }$

Divide the coefficient:

$\small\longrightarrow \sf{21 \div 7=3}$

Divide the base by subtracting the exponents of the base 10.

$\small\longrightarrow \sf{-6(-2) \Longrightarrow -6+2=-4}$

$\leadsto$ Hence, the quotient of the given expression has a coefficient of 3 and the exponent of the base 10 is -4.

$\small\longrightarrow \sf{3 \times 10^{-4}}$

$\huge\underline{\underline{\boxed{\mathbb {ANSWER:}}}}$

$\large \bm{The \: \: quotient \: \: is \: \: 3 \times {10}^{ - 4} .}$

Answer:

Mika's estimated the sum to be 216. The actual sum is 216.27

Step-by-step explanation:

Mika:

189.27 = 189

15.8 = 16

11.2 = 11

189 + 16 + 11 = 216

Actual:

189.27 + 15.8 + 11.2 = 216.27
