What is 4 x b x b x b?
The expression 4 x b x b x b simplifies to 4b^3. This is because when you multiply the coefficients 4 and 1, you get 4. When you multiply the variables b, b, and b, you add the exponents, resulting in b^3. Therefore, 4 x b x b x b equals 4b^3.
What is the exponent form for 2x2x2x2?
A number a multiplied b times (so a x a is b=2, a x a x a is b=3, a x a x a x a is b = 4, and so on) is written as ab. Since 2 is multiplied 4 times, you have 24.
How do you subtract fractions butterfly method?
For the denominator, multiply the denominators together. For the numerator, subtract the second numerator multiplied by the first denominator from the first numerator multiplied by the second denominator: a/b - p/q = (a x q - b x p)/b x q eg: 6/7 - 3/4 = (6 x 4 - 7 x 3)/7 x 4 = (24 - 21)/28 = 3/28
What is the answer for x - 4 3?
okay if x-4=3 then x=7 bcause 4+3=x = 4+3=7 and 7-4=3!
X - 3 divided by 12 - 4x?
(x - 3)/(12 - 4x) = (x - 3)/[4(3 - x)] = (x - 3)/[-4(x - 3)] = 1/-4 = -(1/4)
Is 3 over 4 x b the same as 3xb qver 4?
It is difficult to answer the question because it is still ambiguous. Putting brackets in helps. So: (3 over 4) x b = 3/4*b = 3*b / 4 YES but 3 over (4 x b) = 3/(4*b) is not 3/4*b
What is 4 x b x b x b?
The expression 4 x b x b x b simplifies to 4b^3. This is because when you multiply the coefficients 4 and 1, you get 4. When you multiply the variables b, b, and b, you add the exponents, resulting in b^3. Therefore, 4 x b x b x b equals 4b^3.
What is 3 x b x 4?
12b
How do you solve x2-3x-28 equals 0?
You can use the quadratic formula for an equation of the form a*x^2 + b*x + c = 0. x = (-b +/- sqrt(b^2-4*a*c))/(2*a) In this case: a = 1 b = -3 c = -28 x = (3 +/- sqrt(9 - 4*(-28)))/2 x = (3 +/- sqrt(121))/2 x = (3 +/- 11)/2 x = 7 or -4 Another option is to attempt to simplify the equation into the form (x-a)(x-b) = 0. Sometimes you can do this by observation. For example: 28 = 4*7 7-4 = 3 Thus: (x-7)(x+4)=0 In this case, a and b are known as the "roots" of the equation, with a = 7 and b = -4.
How do you divide two numbers that are in scientific notation?
For example, (4.1076 x 10^3)/(2.8 x 10^4) = (4.1076/2.8) x [10 ^(3 - 4)] = 1.467 x 10^-1 or (4.1076 x 10^3)/(2.8 x 10^-4) = (4.1076/2.8) x [10 ^(3 - -4)] = 1.467 x 10^7
What is the sum of the prime factors of 81?
As a product of its prime factors: 3*3*3*3 = 81 and 4*3 = 12
How to solve x to the third times x to the fourth?
Use x^a * x^b = x^(a+b). x^3 * x^4 = x^7
What is the exponent form for 2x2x2x2?
A number a multiplied b times (so a x a is b=2, a x a x a is b=3, a x a x a x a is b = 4, and so on) is written as ab. Since 2 is multiplied 4 times, you have 24.
What property is (4 3) 12 12 (4 3)?
a(b + c) = ab + ac 4 x 53 = 4(50 + 3) = (4 x 50) + (4 x 3) = 200 + 12 = 212
A florist has 6 banksias 5 wattles and 4 waratahs all the flowers of each kind are different. In how many ways can she make a bunch of 10 flowers if she has to use at least 3 of each kind. 1200?
Must split 4-3-3. Banksia: 3 from 6 = 20, 4 from 6 = 15 Wattles: 3 from 5 = 10, 4 from 5 = 5 Waratahs: 3 from 4 = 4, 4 from 4 = 1 Possible combinations: 4 x B, 3 x each W: 15 x 10 x 4 = 600 4 x Wat, 3 each B & War: 5 x 20 x 4 = 400 4 x War, 3 each B & Wat: 1 x 20 x 10 = 200 Your 1200 is correct.
What are factors in an expression?
Factors aremultiplicativeterms (i.e., they multiply into all the terms). The easiest way to see this is by example.Example 1:a(b+cd)a is a factor and (b+cd) is a factorExample 2:x2 - 9 = (x-3)(x+3)(x-3) is a factor and (x+3) is a factorHopefully you are beginning to notice you can always wrap parenthesis around a factor without altering the order of operations.Example 3:2a(b)(9n-x)+8This is a trick one, but you can factor out a 2:2a(b)(9n-x)+8 = (1)(2)a(b)(9n-x)+(4)(2) = (2)(ab(9n-x)+4)The factors are: 2 and (ab(9n-x)+4)Example 4:If that +8 wasn't on example 3, what would the factors be?2a(b)(9n-x)They would be:2, a, b, and (9n-x)
