Just use the order of operations. First parentheses, then exponents (like "to the third power"), then multiplication and division left to right, and finally addition and subtraction left to right.
Sometimes parentheses can mean multiplication.
(2)(3) is the same as 2*3. 4(5) means 4(5)
Don't get confused though, if there is another symbol between a pair of parentheses it means something different.
(2)+(3) is the same as 2+3. 10-(7) means 10-7
To go to "the power of" a number, you just multiply the number by itself the given amount of times.
2 to the power of 3 means the same as 2*2*2. 11 to the power of 4 is the same as 11*11*11*11.
Try to figure your problem out now and ask if you need any more help.
