Question

Standard Form Helllpppp Plzzz

Answer 1

Answer:

2.4*10^6

Step-by-step explanation:

R = x^2 / y

R = $\frac{(3.8 * 10^5)^2}{(5.9*10^4)}$

R = $\frac{1.444*10^{11} }{5.9*10^{4} }$

R= 2447457.627

to find out what to round of to , you look at the value of x and y

both x and y are rounded of to 2 significant figures. hence for R you should use the same

R = 2447457.627

R = 2.447457627 * 10^6

to 2 sf

R = 2.4 *10^6
