Work out the value<br> of <br> 2. 4510 ×10to the power of 9<br> 1.15 × 10 to the power of 3
Simora [160]

Answer:

The result in standard form is: 2.3 \times 10^{6}

Step-by-step explanation:

Dividing the values:

To find the real part, we divide 2.645 by 1.15. So

2.645/1.15 = 2.3

Finding the power:

Its a division, so we keep the base, and subtract the exponents. So

\frac{10^9}{10^3} = 10^{9-3} = 10^{6}

Result in standard form:

The result in standard form is: 2.3 \times 10^{6}

Find the real numbers x and y.<br> 27+yi= 11-x + 4i
Korvikt [17]

\quad \huge \quad \quad \boxed{ \tt \:Answer }

\qquad \tt \rightarrow \:x = -16

\qquad \tt \rightarrow \: y =4

____________________________________

\large \tt Solution  \: :

\qquad \tt \rightarrow \: 27 + yi = 11 - x + 4i

\qquad \tt \rightarrow \: yi + x = 11 + 4i - 27

\qquad \tt \rightarrow \: x + yi =  - 16 + 4i

By equating both equations we get :

\qquad \tt \rightarrow \: x =  - 16

\qquad \tt \rightarrow \: y = 4
