1,000,000 is the relevant expression.
If there was no 'a' the expression would make no sense. 'in million years' does not make sense.
It depends on the context in which it is defined. If you specifically define 1 M to equal one million in your expression, then yes. If you are working a chemistry problem where the concentration of a substance is 1 M, this means one molar, not one million.
1 million + 1 million = 2 million.
7,700,000
The expression would be written as 16 The value of the expression is 1. 1 x 1 x 1 x 1 x 1 x 1 = 1
1 of a million is a million. 1% of a million is ten thousand.
1/25
The expression is 3b - 1. Not very helpful, but that IS the answer to the question!
Yes, a mathematical expression can have no variables, but such an expression is usually not very useful. An example of a valid expression without variables is: 1+1=2
The answer is b+1. Therefore the algebraic expression for this is b+1
b + 1 is b plus 1 as an algebraic expression.
1 million times 1 million or 1 million squared equals 1,000,000,000,000 or 1 trillion.
