(2x105)/(3x103) + 3x103 * 5x102

AleksAgata [21]

Answer:

1500066.66

Step-by-step explanation:

Given: $(2\times10^{5} )/(3\times 10^{3} ) + 3\times10^{3} \times 5\times10^{2}$

Now, simplifying it.

Using PEDMAS in solving the expression

First opening the parenthesis

= $2\times10^{5} /3\times 10^{3} + 3\times10^{3} \times 5\times10^{2}$

Next dividing the number

as per law of indices, $x^{m} \div x^{n} = x^{m-n}$

= $2\times10^{5-3} /3 + 3\times10^{3} \times 5\times10^{2}$

= $2\times10^{2} /3 + 3\times10^{3} \times 5\times10^{2}$

= $\frac{2\times10^{2} }{3} + 3\times10^{3} \times 5\times10^{2}$

Next multiplying the number as per PEDMAS

as per law of indices, $x^{m} \times x^{n} = x^{m+n}$

= $\frac{2\times10^{2} }{3} + 15\times10^{3+2}$

= $\frac{2\times10^{2} }{3} + 15\times10^{5}$

= $\frac{2\times 100}{3} + 15\times10^{5}$

Next dividing the number as per PEDMAS

= $2\times 33.33 + 15\times10^{5}$

Next multiplying the number as per PEDMAS

= $66.66+1500000$

Now adding the number

= 1500066.66

Answer:

(24-4.00)-4.50/20

Step-by-step explanation: 24 minus 4 would be 20 and you could buy 4 phone cases because 20 divided by 4.50 is 4.4 so 4 times 4 is 16 plus the 2.00 dollars extra from the .50 in the 4.50 so it would be you can buy 4 phone cases.

What is the image of the point (5,-4) after a rotation of 90° counterclockwise about the origin?

Debora [2.8K]

Answer:

(4,5)

Step-by-step explanation:

Rotating a <em>point </em>by 90 degrees <em>counterclockwise</em> would make the y become x and switch it's negative/positive value, and make x the y.

Ex: (x,y) would become (-y,x)
