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 is 3 x a x a x 4 x b?
The result would be 12a2b.
What is the ratio of A to B if 4A equals 5B?
4A = 5B. For finding the ratio A to B take B to the left side of the equation and 4 to the right side. 4 X A = 5 X B ( 4 multiplied by A = 5 multiplied by B) When any number goes to the other side you need to change the sign from + to - or / to X and vice versa. So when we take B to the left side it carries the / sign. Similarly with 4 ) A/B = 5/4 ( The ratio of A to B )
What does the b stand for in the formula y equals mx plus b?
That is the value called the y intercept - value of y when x = 0 for example if y = 3x + 4 b = 4 and y = 4 when x = 0
How do you factor x squared minus 4?
x2 - 4 is a special expression that is referred to as a difference of squares. Whenever an expression is in the format: a2 - b2 it can be factored out as: (a + b)(a - b) In the case of x2 + 4, that would be: (x + 2)(x - 2)
What is the property of 4 equals x plus y then x plus y equals 4?
Symmetry, which states that if A = B then B = A Put A = 4 and B = x + y
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 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 you find the base and height if the height is four times longer then base of a triangle with only the area?
A = (B x h)/2 As h is four times longer than B, we get h = 4 x B Then A = (B x 4B)/2 = (4 x B2)/2 = 2 x B2 thus B=sqrt(A/2) and h=4 x B=4 sqrt(A/2)
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
Can you factorise x2 - 16?
-14
What is 3 x b x 4?
12b
What is 4x squared times 4x squared?
4x^4 or 4x*4x*4x*4x A formula would be (x^a)(x^b)= x^a+b x^a) / (x^b)= x^a-b
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
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.
If the area of a rectangle is 24 square inches its altitude is 4 inches what is the length of the base?
Base = 12 inchesArea = (b x h)/224 = (b x 4)/248 = b x 412 = b
If a and b are rational numbers and a plus b equals a times b what are a and b?
If a = 2 and b = 2, then a + b = 2 + 2 = 4. Further, if a = 2 and b = 2, then a x b = 2 x 2 = 4. The answer is a and b are equal to 2.
