Answers:There are only three rules If you're multiplying, add them If you're dividing, subtract them If you have a power to another power, multiply them Remember that and good luck with your test :-) (After edit) How to remember? A multiply sign is like an add sign turned a bit. A divide sign has a dash in it like a minus. The other one you just need to multiply You'll remember that if you remember the first two :-) Examples 2^4 x 2^3 = 2^7 because 4 + 3 = 7 2^6 / 2^4 = 2^2 because 6 - 4 = 2 (2^4)^5 = 2^20 because 4 * 5 = 20
Answers:Three rules: 1. If the bases of the exponential expressions that are multiplied are the same, then you can combine them into one expression by adding the exponents. 2. If the bases of the exponential expressions that are divided are the same, then you can combine them into one expression by subtracting the exponents. 3. When you have an exponential expression raised to a power, you have to multiply the two exponents. Scientific notation problem: 10 x 1.2^8
Answers:X^5 when you multiply the same variables with different exponents, you just add them.
Answers:Ok, we lets simply the outer two exponents first (9x^4)(27x^0) This gives us 9*27*x^(4+0) = 243x^4 For the second, we get 16x^-4 = 16/x^4 How do you do this? You expand the enter and you multiply the exponents of exponents and you add when exponents are added together. Another way to look at this (-3x^2)^2(3x^0)3 is (-3^2x^(2*2)) * (3^3x^(0*4))
