You will be shown an excerpt from a computer science scientific research paper, followed by a question about the paper. Please answer the question. Do not include any text in your response other than the answer.

Context: The basic implementation structure is illustrated in Table 1.For a block of size h\times w, expansion factor t and kernel size k with d^{\prime} input channels and d^{\prime\prime} output channels, the total number of multiply add required ish\cdot w\cdot d^{\prime}\cdot t(d^{\prime}+k^{2}+d^{\prime\prime}).Compared with (1) this expression has an extra term, as indeed we have an extra 1\times 1 convolution, however the nature of our networks allows us to utilize much smaller input and output dimensions.In Table 3 we compare the needed sizes for each resolution between MobileNetV1, MobileNetV2 and ShuffleNet.

Question: The authors mention that their primary network has a compute cost of 300 million multiply-adds. By how many orders of magnitude would this compute cost increase if the authors did not use bottleneck layers?
The compute cost when using traditional layers are h · w · d' · d'' · k^2, so the cost would be increase by a factor of d'' · k^2/t(d' + k^2 + d'').
