Answer:
If something is "to the power of 15" then it means it is multiplied by itself 14 times (one less than 15 as the original number is already to the power of 1).
An example:
So 2 to the power of 15, which we write as 215 = 2 * 2 * 2 * 2 etc... (so we have 15 written 2's in total meaning we will make 14 multiplications) is equal to 32,768.
Answer:
10
Step-by-step explanation:
-10-(-20)
A negative and a negative is addition
-10+20=10
Step-by-step explanation:
2x2 + 10 - 3x - 3 + 3
Solving like terms
2x2 - 3x + 10
Option B is the correct answer
Answer:
Rs. 450 and Rs. 300
Step-by-step explanation:
Step 1: Add the ratios; 3 + 2 = 5
Step 2: Put each ratio over the total, to see what proportion each part receives 3/5 and 2/5
Step 3: Multiply the 750 by the fraction to calculate the proportion that each part contains
3/5 x 750 = Rs. 450
2/5 x 750 = Rs. 300
